Figure 2

Predicted trajectories of immunoglobulin G (IgG) levels over six months by naïve status at T0 between gender. Predicted trajectories of IgG levels, after base 10 exponentiation of predicted values and 95% confidence interval limits. Figures represent the predictions for naïve HCWs (A) and for HCWs with previous titers >50 AU/ml (B). Median age was used on these estimates. The dotted horizontal lines represent 4160 AU/ml and 50 AU/ml levels. HCWs = healthcare workers; AU = arbitrary units.
